Parameters: %1 = Channel number %2 = Block number, label Definitions: The label of this bl ock already exists. If the NC program is compiled off-line, the entire progr am is compiled block for block. During this procedure all multiple labels are recognized; this is not always the case with on-line compilation. (Only the actual program run is compiled here, i.e. progr am branches that are not passed through in this run are disregarded and could therefore contain programming errors). Reaction: Correction block is reorganized. Interface signals are set. Alarm display. Remedy: Press the NC Stop key and select the function "C orrection block" with the softkey PROGRAM CORRECT. The correction pointer is positioned on the bl ock where the displayed label occurs for the 2nd time. Use the editor to search the part program where this label occurs for the 1st time, and change one of the names. Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program. Diagnostics Manual (DAsl), 03/2009
